The Greenhouse Effect The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sunlight in to make heat, but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts, and climate changes which could alter our way of living.

Meaning of Global Warming: One of the global problems is the threat of a long run increase in the surface temperature of the earth. This goes under the name of global warming or sometimes the green house effect as it is popularly called, are long-term and largely irreversible.
The principle of greenhouse is that the enclosing gases allow the passage of incoming sunlight but trap a portion of the green house above the outside temperature. Certain gases in the atmosphere absorb this radiant energy and re-emit the heat back to the Earth Burning fossil, deforestation and production of certain synthetic chemicals are releasing large quantities of heat trapping gases into the atmosphere.
A green house is that body which allows the shorter wave length radiation. The glass of green house and the CO2 layer does not allow the heat to be reradiated and warm up the entire atmosphere.
Green House Effect and its Sources: Certain gases in the atmosphere absorb this radiant energy and re-emit the heat back to the earth. Those gases which are capable of absorbing and re-emitting the heat radiation are called green house gases.
As we go higher the air thins out gradually except for the layer in the atmosphere called ionosphere which is composed partly of electrons and positive ions, the rest of the atmosphere is composed mostly of neutral molecules.
We can see the sun and stars clearly through the atmosphere because the atmosphere is transparent to visible radiation.
Much of the visible light of short wave length from the sun that reaches the earth is reradiated as long wave length infra red which is readily absorbed by CO2 and other green house gases in the atmosphere.
Thus carbon dioxide layer acts like a blanket and traps the infrared rays. The heat from the surface of the earth warms up the green house gases. These gases in turn emit some heat into space and some back down to the surface.
These gases are released into the atmosphere by different human activities. Carbon dioxide CO2 is the main offender in the global warming crisis, according to the consensus of CO2 is responsible for about half the global warming; other pollutants and the other green house gases account for the rest.
The global temperature has risen by 0. So finally reduction in the Emission of Greenhouse Gases calls for: Contribution to Global Warming: Imagine a world of short of water, energy and all other things that we take for granted in our daily life.
Imagine in other words, a world reduced to a nasty, brutish existence because of the competition for scarce resources. For the sad reality is that the world is going to face a catastrophe if it continues to consume natural resources the way it is doing today with no thought of the morrow.
Contrary to what one might believe the earths resources are finite, there are limits to how much we can exploit them. No single country contributes more than small fraction of green house gases. Data for suggest that the developed countries contribution of CO2 emission was 3.
Developing countries on the other hand, account for only 1. The CO2 emission is projected to increase by 2. USA is the largest contributor globally accounting for nearly 18 per cent.
Responses to Greenhouse Effect:Global Warming and the Greenhouse Effect The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earth's lower atmosphere have on surface temperatures.
The greenhouse effect is the phenomenon where light from the sun is allowed to pass through a transparent medium to a planetary surface, but on getting radiated, the energy is absorbed by the greenhouse gases, like carbon dioxide, Ozone, methane and .
The Greenhouse Effect This essay is going to describe what the greenhouse effect is and what it srmvision.com is also going to say what causes the greenhouse effect and the consequences of it. Words Essay on Green House Effect Article shared by Green House Effect is a term used first by J.
|It is a general topic of essay or speech for students in the schools or colleges.|
Fourier in and it is also called global warming, atmospheric effect or C0 2 problem. Green House Effect and Global Warming Essay 3 ( words) Greenhouse effect is a process caused by the green house gases during which thermal radiations of the earth’s surface gets absorbed which again re-radiated to all directions instead of escaping back to the space.
